TCONTCCMHCM04A Wiring & Operating Instructions
The core function of the protocol converter is to convert Modbus protocol
into BACnet protocol, implement Modbus device integration into BACnet
network. That is, the gateway acts as a Modbus Master (master station) and
supports connection of 4 Modbus Slaver devices. TCONTCCMHCM04A is a
standard BACnet network device in the BACnet network, and the user can
map the device data points in the MODBUS network one by one to the data
points in the BACnet network. The gateway provides the BACnet service
interface, and the third-party BACnet Client software integrates the Modbus
Slaver device into the system through the gateway.
